I'm thinking it should be possible but i have only basic arduino experience (few wireless sensor projects but that's it). Arduino is just going to organize the data each frame and send it over wifi to a PC that will do all the heavy lifting. 14 bytes per vector component with the sensors I plan on using which we will round to 16 bytes since I might pad the values in memory should be 16 x 6 = 96 bytes per sensor x 18 sensors x 60 fps x 8 bits per byte = ~830k bits per second (103.7k bytes per second). Seems well within the range of a xbee. Is that reasonable with a Due and Xbee combo?
Thing is at my work we use Magnetometers and Accelerometers to calculate orientation but motion capture suits in the industry seem to do accelerometer and gyroscopes which confuses me since you need a calibrated reference to work with a gyroscope (I think) because it just reads changes in rotation not absolute rotation (unless I'm not understanding something by reading the white pages on different ones). Anyone who worked with a accelerometer and gyroscope able to explain to me how you get absolute orientation using that combo? I have some parts in the mail so I could probably answer the question myself in a week or so but always like hearing from people that know a bit more than me.
